RE'TORT FO-RMAKING BISULPHIDE OF CARBON.

SPECIFICATION forming part of Letters Patent No. 464,747, dated December 8, 1891.

' I Application filed February 18, 1891- Serial No. 381,909. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH BECK, a citizen of the German Empire, residing at the city of Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Retorts for Making Bisulphide of Carbon, of which the following is a specification.

This invention relates to an improved retort for making bisnlphide of carbon by which the yield of bisulphide of :carbon is increased and the exchanging of worn-out retorts facilitated, which was connected with considerable expense and loss of time in the retorts here- 5 combination, with a retort for evaporating sulphur, which is located in a separate furnace, of a retort filled with charcoal and a pipe for connecting the evaporating-retort with the charcoal-retort, said connecting-pipe being located outside of the furnace and provided with a slide-piece for shutting oif the connection between the retort-s.

The invention consists, secondly, of a charcoal-retort having a flange at its, upper end, said flange resting on transverse bars supported by exterior upright bars of the furnace, which has a temporary front wall, so as to facilitate the exchanging of worn-out retorts.

In the accompanying drawings, Figure 1 represents a vertical longitudinal section of my improved retort for making bisulphide of carbon. Fig. 2 is a horizontal section on line 2 2, Fig. 1. Fig. 3 is adetail side view of the retort for distilling the sulphur. Fig. 4 is a front elevation of a modified form of apparatus, showing two 'charcoal-retorts connected with one evaporating-retort; and Fig. 5 is a vertical transverse section on line 5-5, Fig. 4, showing the connection of the charcoal-retort withthe condenser.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents a furnace, which is open in front, so that it is U-shaped in plan, and which is provided with a grate a and.an arch a above the grate, on which arch rests a cast-iron retort C, preferably made of L shape. The lower part of the retort C extends in forward direction through the front wall of the furnace, which is closed tofore used; and the invention consistsot tlfe temporarily in front of the upper part of the retort by suitable brick-work. Around the retort are arranged lines for the products of combustion, said fines communicating with a suitable chimney. In the front wall ofthe lower part of the retort 0 is' arranged a hand-hole and hand-hole cover for cleaning the interior of the retort. The retort C is provided at its upper part with an annular 6o flange b, which rests on transverse wroughtiron bars (1, that are supported by vertical bars d. The transverse bars 61 are threaded at the ends, which pass through the vertical .b h rei ey e emonalbly. held by. 65

'silitabl'd'serew-nuts'd a's'shown in Fig. 1.

The retort O is supported on the transverse bars (I, so that the retort can freely expand by springing the bars and the retort be readily removed from the furnace A (the front bar (1 and the front wall of the furnace being removed) when it is necessary to exchange a worn-out retort and replaced when the new retort is placed in position. The retort.O is provided at its upper end with a chargingfunnel and valve made of the usual construction. I

The L-shaped retort C is charged with charcoal, which by the fire below the retort is heated to incandescenee, the sulphur vapors being conducted through the charcoal, so as to form vapors of bisulphide of carbon. The sulphur-vapors are supplied from a separate retort D, which is supported in a separate furnace B and connected by a pipe E with 85 the charcoal-retort C, the pipe E being provided with a slide 8 for 'shuttrng 01f the connection with the evaporating-retort D when necessary.

The sulphur-retort D is provided in its front wall with a hand-hole and hand-hole cover like the retort O, and at its rear part wit-h a f unnel-shaped supply-hopper, through which the sulphur is inserted into the retort. The slide .9 is preferably made of good sheetiron that is covered with a suitable asbestus preparation or with aluminium, as these substances are capable of resisting the corroding action of the sulphur-vapors, while they permit the easy movement of the slide.

The connecting-pipe E, that connects the front part of the evaporating-retort D with roo the front part of the lower portion of the retort G, is located outside of the furnace-walls, so as to protectit against the action of the fire and prevent its too rapid deterioration by the influence of the sulphur vapors passing through the same.

It is preferable to arrange a charcoal-retort at each side of the sulphur-evaporating retort, as thereby thedistillation of the sulphur can be made continuous, as when one retort is charged the vapors can be conducted into the other retort C by means of the slide 3, and so on alternately.

In Fig. 1 the connection of the evaporatingretort with a single charcoal-retort is shown, while in Fig. 4: the evaporating-retort is shown as connected with two charcoal-retorts C.

The vapors of bisulphide of carbon, which are formed by the contact of the sulphur vapors with the incandescent charcoal in the retort C, are conducted from the upper part of the same through a pipe F to a condenser, which is formed of vertical pipes G and K, the lower parts of which terminate in closed receptacles L and M for the liquid bisulphide of carbon. The pipe K is connected at its upper end with the pipe G and surrounded by a cooling-jacket K, that is supplied with water at the upper end, while an outlet-pipe conducts ofi the water at the lower end. The liquid bisulphide of carbon collected in the closed receivers L and M is drawn by suitable faucets 0, while the non-condensing vaporssuch as sulphuret hydrogen are conducted off through a pipe N from the receiver M. A Wall WV separates the retorts from the condensers, as shown clearly in Fig. 5.

The advantages of my improved retort for making bisulphide of carbon are that by arranging a separate retort for the sulphur vapors a more effective utilization of the sulphur and a greater yield of bisulphide of carbon is obtained, as the vapors are combined in a more effective manner with theincandescent charcoal, and as the operation can be more quickly and conveniently interrupted. Secondly, that by arranging two or more retorts in connection with the evaporating-retort the distillation of the sulphur can be carried on continuously and the formation of bisulphide of carbon be also made continuous, as when one retort is charged with charcoal the other is supplied with sulphur, and vice versa; and, thirdly, that by suspending the retorts from a supporting-frame they can evenly expand. and do not wear out at the bottom, while they can also be more conveniently removed from the surrounding walls of the furnace whenever a retort is worn out by use and replaced by a new one.

It the retorts were walled up, it is obvious they could not expand without spreading the walls and injuring the furnace, whereas the cross-bars spring slightly and permit such expansion. Furthermore, the furnace being U- shaped in plan, when the front bar d is removed the retort can be withdrawn bodily from the furnace, as will be clear,

Having thus described my invention, I claim as new, and desire to secure by Letters Patent-- The combination, with a furnace of approximate U shape in plan, upright bars at the sides of said furnace, cross bars having threaded ends passing through said upright bars, and nuts on said ends, of an L-shaped retort located in said furnace, with its lower end projecting through the front removable wall thereof, and an annular flange on said retort resting on said cross-bars, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
